2008 States Of Matter

  1. 1. States of Matter November 9, 2009
  2. 2. Objectives <ul><li>Distinguish between four states of matter </li></ul><ul><li>Explain the kinetic theory of matter </li></ul><ul><li>Recognize energy as the reason for phase changes </li></ul>
  3. 3. Physical Property <ul><li>Characteristic that distinguishes one type of matter from another type </li></ul><ul><li>Can be observed without changing the identity of the substance </li></ul><ul><li>Ex: mass, weight, volume, density, color, shape, hardness, texture, phase of matter </li></ul>
  4. 4. Physical Changes <ul><li>A new substance is NOT formed </li></ul><ul><li>Change in color, size, shape, phase of matter, etc. </li></ul><ul><ul><li>Cutting paper </li></ul></ul><ul><ul><li>Freezing water </li></ul></ul><ul><ul><li>Melting butter </li></ul></ul><ul><ul><li>Squeezing lemons </li></ul></ul><ul><ul><li>Mixing Kool-aid powder with water </li></ul></ul>
  5. 5. Kinetic Theory of Matter <ul><li>Matter is made up of particles which are in continual random motion. </li></ul>
  6. 6. FOUR STATES OF MATTER <ul><li>Solid </li></ul><ul><li>Liquid </li></ul><ul><li>Gas </li></ul><ul><li>Plasma </li></ul>
  7. 7. STATES OF MATTER <ul><li>Based upon particle arrangement </li></ul><ul><li>Based upon energy of particles </li></ul><ul><li>Based upon distance between particles </li></ul>
  8. 8. <ul><li>What would it take for matter to move from one state to another? </li></ul>
  9. 9. Energy determines the state!
  10. 10. SOLIDS <ul><li>Particles are tightly packed, vibrating about a fixed position. </li></ul><ul><li>Have a definite shape and a definite volume. </li></ul>
  11. 11. Types of Solids Amorphous Crystalline
  12. 12. Crystalline Solids <ul><li>arranged in repeating geometric patterns called crystals </li></ul><ul><li>salt, sugar </li></ul>
  13. 13. Amorphous solids <ul><li>molecules are arranged in a random manner </li></ul><ul><li>can lose their shape under certain conditions </li></ul><ul><li>Tar, candle wax, glass </li></ul>
  14. 14. <ul><li>Animation-Heating </li></ul>
  15. 15. LIQUID <ul><li>Particles are tightly packed, but are far enough apart to slide over one another. </li></ul><ul><li>Have an indefinite shape and a definite volume. </li></ul>
  16. 16. GAS <ul><li>Particles of gases are very far apart and move freely. </li></ul><ul><li>Gases have an indefinite shape and an indefinite volume. </li></ul>
  17. 17. PLASMA <ul><li>Have an indefinite shape and an indefinite volume. </li></ul><ul><li>Very good conductor of electricity and is affected by magnetic fields. </li></ul>A plasma is an ionized gas.
  18. 18. The Sun is an example of a star in its plasma state
  19. 19. Some places where plasmas are found… Flames
  20. 20. Lightning
  21. 21. Aurora (Northern Lights)
  22. 23. STATES OF MATTER SOLID LIQUID GAS PLASMA Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles
